How does the rabies vaccine work? If the virus sneakily gets to your brain, why after vaccination it starts detecting the virus given it was not possible to find it before?

Rabies travels very slowly. Assuming you aren’t bit on the head or neck, it takes weeks or months for the rabies virus to travel through your nervous system to your brain.
The rabies vaccine trains your body to recognize and fight the virus BEFORE it starts causing serious brain damage. Naturally, our bodies take so long to catch on to the virus that it has already caused lethal brain damage before the body is able to start fighting it off. Luckily, the virus moves so slowly that the vaccine can train the immune system before the virus can reach the brain.
